The original Gemini was equipped with a 1492 cc imported four-cylinder engine. Power was at 5,400 rpm, for a claimed top speed of . This imported engine made the car rather expensive, however, and when the
Hyundai Pony was introduced Saehan's market share dropped precipitously. A measure of popularity was retained as the Gemini was the only compact car in South Korea with an available automatic transmission. In 1981, in an attempt at consolidating the South Korean transportation industry which had been hard hit by the 1980 recession, the new military dictatorship of
Chun Doo-hwan forced
Kia to give up production of its
Brisa and focus entirely on light trucks. In return, Saehan and Hyundai had to give up this segment of the market, while a planned merger of the two did not come to fruition. Not only did these changes allow Saehan a bigger share of the market, but they were also able to use the domestically built 1.3-liter (
Mazda TC) engine that Kia no longer had any use for, which lowered the price of the new Maepsy considerably. The facelifted Saehan Maepsy was introduced in February 1982, with the 1.3-liter engine using
LPG and producing (SAE) for a top speed of . The 1.5-liter model claimed (SAE) but somehow had a slightly lower top speed of ( for the automatic). In 1983, the name was changed to Daewoo Maepsy. In September 1983, for the 1984 model year, the car received another facelift, with bigger rectangular headlamps, becoming the Maepsy-Na in the process. The rear was also changed, echoing the design of the 1979
Isuzu Gemini. The
XQ engine was built by Daewoo from April 1984 and installed in the Maepsy beginning in September, meaning that Kia's 1.3-liter version was retired. Claimed power for the earlier 1.5 was now only as South Korea had switched to using
DIN ratings, but when the XQ arrived Daewoo once again used SAE gross and claimed . Between 1982 and 1989, 400,000 Maepsys and Maepsy-Nas were built. Production of the regular sedan ended in July 1986 when the Racer/LeMans was introduced although a version intended for taxi usage continued to be produced until 1989 as the "Daewoo Maepsy Sigma". The Sigma was fitted with an LPG-powered 1.5-litre of Opel origins, as also used in the LeMans. This engine produces at 5,500 rpm. == Saehan/Daewoo Max ==
